Note that the data points (points of measurement) are automatically connected by straight lines, which
define the output values of any points off these data points. The inclination between the last two data
points is extended as a straight line beyond the last point until it reaches the end of the measuring
range. If the intended welding current or voltage is not output due to a fluctuation in the Power Source’s
power supply voltage, adjust the output by specifying a correction value. The figure (welding current
output characteristics) shows how a correction value works.
The following are the three types of the Power Source condition files. Each file consists of two
windows.
The execution file is used to set the condition file of the Power Source being used. The user registered
file is used by the user to save the Power Source condition files, and the data for eight models can be
registered. Yaskawa also offers initial value files which contain common Power Source characteristics.
Data for 64 models have already been registered. A Power Source condition file can be set only by
reading from either the user registered file or initial value file to the execution file. When it is necessary
to make adjustments to the data, refer to section 9.12.4 "Editing the Power Source Condition Files".
9.12.2 Specifying Welding Voltage when Synergic Power
Supply is Used
When a synergic power supply is used, the NX100 requests the user to specify the welding voltage by
a ratio against the proper output value (not by the output value as conventionally done).
For that, the voltage characteristics associated with a certain welding current output value must be
determined by measurement, and the results should be stored in the Power Source condition data file
as representative values. The welding current output value for the measurement should be a value that
is assumed relatively often in actual situations. Each of the provided Power Source condition data files
already contains the representative values for the associated Power Source model.
